  • Air freshener with multiple air flow paths
    Patent number: 11986576
    Abstract: An air-treating apparatus for dispensing a volatilizable material, such as air freshener fragrance, into the atmosphere of an enclosed area. The apparatus includes a housing and a reservoir of the volatilizable material therein, and also includes a multiple-configured air flow path arrangement which enables air-flow through the apparatus in multiple configurations. The apparatus enables use of the consistent delivery rates of a volatilizable material producing a more consistent delivery rate than normally achieved with such devices.

  • Organotin polymers method of making them and paints containing them
    Patent number: 4380599
    Abstract: Organotin polymers for use in marine anti-fouling paints contain pendent groups having the general formula --O.CO.R.sup.1 CO.OSnR.sub.3 where R is C.sub.1 to C.sub.10 alkyl, aryl, aralkyl or alkaryl, and R.sup.1 is a saturated or unsaturated aliphatic or aromatic C.sub.2 to C.sub.10 group. The polymer may be made by reacting a hydroxyl-containing polymer, e.g. styrene/allyl alcohol, with a carboxylic acid anhydride under ring-opening conditions and reacting the resulting carboxyl-containing polymer with an organotin compound.
